Outlook Archinve Addin-in

We are using McAfee email archive service.  They have a plug-in for Outlook that allows users to search their own archive.  For me, as of late it has begun to pop up an error every time I change a folder in outlook.  See error text below in code section.  

Strangely it is following me from physical XP to XenDT Win7.  We don't have any profile mangement within the XP environment or I would think it is a profile issue.

It would pop up occastionally error before, but now it occurs on each new folder selection within outlook.

The action that preceeded this was that I sent a search result folder to the deleted items.

McAfee, while offering this for download (http://www.mcafee.com/us/downloads/saas/archive-addin.aspx) says it was written by Microsoft and offered as a convenience, but not supported.

Outlook v.2007.  Exchange 2003.
